The physical mechanism for vortex merging

C Cerretelli, CHK Williamson - Journal of Fluid Mechanics, 2003 - cambridge.org
In this paper, we study the interaction of two co-rotating trailing vortices. It is well-known that
vortices of like-sign ultimately merge to form a single vortex, and there has been much work …

Analysis and treatment of errors due to high velocity gradients in particle image velocimetry

P Meunier, T Leweke - Experiments in fluids, 2003 - Springer
This paper deals with errors occurring in two-dimensional cross-correlation particle image
velocimetry (PIV) algorithms (with window shifting), when high velocity gradients are …

Physics of vortex merging

P Meunier, S Le Dizès, T Leweke - Comptes Rendus Physique, 2005 - Elsevier

Long-wave instability of a helical vortex

HU Quaranta, H Bolnot, T Leweke - Journal of Fluid Mechanics, 2015 - cambridge.org
We investigate the instability of a single helical vortex filament of small pitch with respect to
displacement perturbations whose wavelength is large compared to the vortex core size. We …
